      [tools] Improve grokdump.py · 5ca9632e
      Camillo Bruni authored 
      - Add new address markers:
   T: tagged pointer in the minidump
   C: address into a module in the minidump
   S: pointer into the exception stack in the minidump
   *: other address in the minidump
- Show ASCII decoding of address in dd
- Display potential frame markers on the exception stack:
   00000032212fdae8: 0000000300000000   ........ Smi(3) EXIT frame marker
- Display relative addresses, useful to detect stack frames:
   00000032212fdb68: 00000032212fdb98 S ........  [+6]=00000032212fdcb0 S
   00000032212fdb70: 0000010ff5ca0a84   ........

   00000032212fdb90: 0000000d00000000   ........ Smi(13) INTERNAL frame marker

      [heap] Use HashMap as scratchpad backing store · 55422bdd
      mlippautz authored 
      We use a scratchpad to remember visited allocation sites for post processing
(making tenure decisions). The previous implementation used a rooted FixedArray
with constant length (256) to remember all sites. Updating the scratchpad is a
bottleneck in any parallel/concurrent implementation of newspace evacuation.

The new implementation uses a HashMap with allocation sites as keys and
temporary counts as values. During evacuation we collect a local hashmap of
visited allocation sites. Upon merging the local hashmap back into a global one
we update potential forward pointers of compacted allocation sites.  The
scavenger can directly enter its entries into the global hashmap. Note that the
actual memento found count is still kept on the AllocationSite as it needs to
survive scavenges and full GCs.

      V8 Microtask Queue & API · 6b5a4cde
      rafaelw@chromium.org authored 
      This patch generalizes Object.observe callbacks and promise resolution into a FIFO queue called a "microtask queue".

It also exposes new V8 API which exposes the microtask queue to the embedder. In particular, it allows the embedder to

-schedule a microtask (EnqueueExternalMicrotask)
-run the microtask queue (RunMicrotasks)
-control whether the microtask queue is run automatically within V8 when the last script exits (SetAutorunMicrotasks).

      Instance-type-related fixes and cleanup. · f0305bd8
      svenpanne@chromium.org authored 
      Things got quite a bit out of sync (don't we all love copy-n-paste?):

   * TypeToString didn't handle SLICED_STRING_TYPE,
     SLICED_ASCII_STRING_TYPE, FIXED_DOUBLE_ARRAY_TYPE,
     JS_FUNCTION_PROXY_TYPE and JS_DATE_TYPE.

   * INSTANCE_TYPE_LIST was missing entries for
     SLICED_ASCII_STRING_TYPE, JS_SET_TYPE, and JS_MAP_TYPE.

To improve this maintenance nightmare a little bit, the missing
instance types were added to the INSTANCE_TYPE_LIST macro and this
list is now used via our beloved 2nd order macro technique in
TypeToString. As a side-effect, the strings returned by TypeToString
have a "_TYPE" suffix now, but this doesn't really matter and is a
small price to pay for consistency.

Removed INVALID_TYPE on the way, it had no real use.
